NATHAN COFNAS: Look under the hood on climate change “science” and what you see isn’t pretty.
Let’s unpack this a bit, using actual science. The proportion of carbon dioxide in the earth’s atmosphere is currently about 400 parts per million (ppm). The Cambrian explosion—when most animal lineages first appeared—occurred a little more than 500 million years ago when, according to all estimates, carbon dioxide levels were several times higher than today. The atmosphere of Venus is 965,000 ppm carbon dioxide, enveloped in clouds of sulfuric acid. And Venus itself is almost 26 million miles closer to the sun than Earth.
So Hawking’s claim that the earth is on the “brink” of becoming like Venus is preposterous. Even the Intergovernmental Panel on Climate Change explicitly notes that the Earth will not experience a runaway greenhouse effect such as might have occurred on Venus.
What is really disturbing, though, is that Hawking has flagrantly given up on even the pretense of engaging with actual science. He speaks entirely from authority: I am a scientist. Adopt this political policy that I favor or suffer fire and sulfuric acid. The threatened punishment for noncompliance substitutes sulfuric acid for the regular sulfur (brimstone) that features in old-fashioned religion. As far as the justification for the claim, there is no important difference between this and a religious statement that is supposed to be believed simply because it issues forth from a high priest.
The real concern is how far the Climate Change Cult will go to smite the wicked.
